Electronic Throttle Corrector JETTER electronic MRS II Control Key Fob for Mercedes vehicles

JETTER MRS II Electronic Throttle Corrector with Control Key Fob for Mercedes vehicles. The module connects to the accelerator pedal position sensor connector without modifying car parts and contains a microprocessor that converts pedal position signals and transmits them to the engine management controller. JETTER modifies the relationship between pedal position and throttle valve to remove opening delay, supplying the working mixture earlier to increase torque and power response and improve acceleration dynamics while maintaining immediate throttle closure when the pedal is released. The device is maintenance-free and is designed to be electrically transparent to the engine diagnostic system; it does not change algorithms for fuel supply, ignition, ABS, TCS and other vehicle control systems. Fuel consumption may increase or decrease depending on driving style (typical change up to ±0.4 l/100 km). Installation is straightforward, but due to connector and harness design it is recommended to have the device installed at a specialized service station. More information: Jetterauto.ru

Advantages

Provides a faster and more direct connection between accelerator pedal position and throttle valve without mechanical modification of the vehicle. The handheld control key fob allows on-the-fly adjustment of throttle correction. The unit is plug-and-play to the pedal sensor connector, maintenance-free, and designed to remain compatible with vehicle diagnostics and safety systems.

Suitable for

• Mercedes A-, B-, C-, CLA-, CLK-, CLS-, E-, G-, GL-, GLA-, GLE-, GLC-, GLK-, GLS-, M-, S-, SL-, SLK-, SLS-classes and SPRINTER models listed in the vehicle compatibility table
• Drivers who want quicker throttle response and improved acceleration dynamics
• Workshop installs where remote control of throttle correction is required

How to use

Connect the JETTER MRS II to the accelerator pedal position sensor connector following the vehicle-specific wiring layout. After connection, use the included control key fob to select the desired throttle correction setting while monitoring vehicle behaviour. The unit immediately adjusts signal conversion so the throttle valve responds with reduced lag; normal pedal release behavior is preserved. If unsure about connector access or wiring, have the device installed by a professional service technician to avoid damage to the harness.

Usage recommendations

For safest operation, verify compatibility with your specific Mercedes model and year from the compatibility list, and consider disabling traction-control systems using the standard vehicle controls when testing maximum response. If you are not experienced with vehicle electrical systems, request installation at a specialized service station.
